The current (I)-voltage (V) plot of a certain electronic device is given above. The device is

true or false: Computer is an electronic device.

A 'rectifier' is an electronic device used to convert

To measure the current in an electric device

The current-voltage graph of a device is shown in figure. The resistance is negative in region.

The current-voltage graph of a device is shown in figure. The resistance is negative in region.

Alternating current flowing through a certain electrical device leads over the potential difference across it by 90^(@) . State whether this device is a resistor, capacitor or an inductor.

Table given below shows the current (I) voltage (V) relationship of a device. Draw V-I graph. With the help of the graph explain whether the device is showing ohmic or non-ohmic behaviour
